THOMAS MELVILLE, 0F DUNEDIN, NEW ZEALAND Do'rLAND-Dasn-CODE Reconnu..

Be it known that I, Tnoiris Mrznvitnin a citizen of the Dominion of New Zealand. and residing at 40 George street, Dunedin, in the Provincial District of Otago, in the Dominion of New Zealand, have inventedl certain new and useful Improvements in Dot-andDashC0de Recorders, of which the following is a specification.

The invention relates to an apparatus for recording flash light signals transmitted by l what is known as the Morse or dot and dash system.

By the use of my invention signals ma)Y be received by those who are not acquainted with the dot and dash code system. and i the message received is' written in ordinary l Ihe lettersl of a message received nre rei corded by means of metal type which prints i the letters of the alphabet in the manner of g a typewriter by means of a carbon rih bon superposed upon a ribbon of paper? The particular letter rinted depends upon the positions relative y to each other of a series of `slide bars which provide that. only one letter may be printed at a time by the action of a de ression bar. Said bar ex tends across tie machine, and when depressed by the operator engages with the tuate the type bars. The slide bars are actuated by the operator who moves a hand lever to the right or left :recording to whether the station from which the signal is being received is transmitting a dot or a dash. The lever is vibrated a number of times according to the number of dots and dashes representing the letter of the signal, and then the depression bar is struck by the operator, -the corres onding type being thereby actuated and t e letter printed upon the paper ribbon Areferred to.

I will now describe my invention in detail by the aid of the drawings, whereing-- Figure 1 is a front elevation of .my improved apparatus;' Fig. 2 is a plan with some of the arts removed; Fig. il is a side elevation looking toward the right hand side of the machine; Fig. 4 is a side elevation'. looking toward the left hand side of the machine; Fig. 5 is a front. elevation, and Fig. 6 is a side elevation of the operating lever and parts actuated thereby; Fig. 7 is a side sectional elevation of the parts shown in Figs. 5 and 6; Fig. 8 is a rear elevation Specitlcation of Letters Latent.

lel'ore describing` the details of the drawyugs l will indicate broadly what. the mechatif-m is intended to do. The operator'stands in front of the machine and grasps lever A. For every time a flash signal is transmitted from the/Sending station he moves the lever for a dot flash to the right, and for a dash" flash to the left. Then the number of dots and dashes constituting the code si nal of a letter have been received, he puls the lever toward him, and then depresses the depression bar B-r which in Fig. 2 is shown in dotted lines. This has the effect ot' causing the type letter corresponding to the signal sent to strike upon the carbon ribbon C and to print the letter upon the paper-ribbon D.

Referring now to details: The various type letters 1 for printin the letters of the alphabet are fixed upon ll crank levers 2 (see Figs. 1. 3 and 29) each journaled in an independent 'aw 3 fixed upon the quadrant bracket 4. he short arm of the bell crank lever is connected by a Vertical rod 5 with a horizontal lever t3 journaled upon a bar 7 (Fig. 2) extending across the machine. Upon the end of the lever slides a striking head 8 (see Figs. 25, 26 and 28) which is pushed toward the end of the lever by a spiral spring 9 upon a pin 10. brojecting from the end of the striking head. the spring being interposed between the striking head and bracket 11. upon the lever. The ty e lever-sare similarly constructed andhave tlie saine operating parts, itis therefore necessary t'o describe only one set., the same indieating nmnerals being used to indiate correspor lintr parts` upon the other sets. Fight .superpowd stop plate.` 3l. 3;. Iti. 34, 15. 3th 8T. and I. ,shown in detailed platt in Fics. "l to zo int-lusite. extend across the machine with their rear edges in contact with tite striltinf; heads` o. as shown in Figs. t and t. liaeh ot the -top plates is acted upon b v two springs. one at each end, whi-'h normally tends to push them away from the ,strikingr heads. y'l'he compression spriu;V 'o engages over a snih il projecting from the plate. and at the other end over the end ot' al1 adjustingY screw 2:. which passes through the ltraclft't Il. l'pon the other entl ofthe plate a similar compression spring it. Figs. t and 22 engages over the snib 25 at one end. and at the other end over the afl justine .stnyw it] which passes through a bracket LT. The depression bar l is fixed at each end upon the lewrs 2S and 29 which are pivoted on the cross bar T and are respectively rottnterbalaneed by the weights and 31a. Figs. L. il and 4.

To print a letter upon the paper ribbon D it istieeessarv that the lever (3 operating the type hat` .shall be depressed at itsouter end. This depression is eti'ected by the depression bar l which contacts with the particular striking,f head which may be pro jected into its path. The stop plates normally prevent any of the striking heads from being projected. To provide for the jn'ojeetion of each of the striking heads in-` dependently of the others, ythe stop plates have a series of "ecesses which may be brought into superposetl correspondence by a number of ditl'erent arrangements of the plates relatively to each other, the movement of one or more of the stop plates being necessary to permit a striking head to pass sutiieientlj.' far into the superposed series of recesses in the several stop plates to come into the path of the depression bar.

The stop plates are independently shown in Figs. 13 to 20. Fie'. 13 showing the uppermost plate Si. and the foliowing figures the plates 3:2. 15P., iti. 3o. Bti, 3T. and 3S beneath it. arranged in regular order. lt will be seen that the plate Fig. il has a plurality of'reeesses including the recess 39 and the .succeeding plates have recesses 4th 4l. 4Q, 43,

' 4 l. and 4.31. similar to the recess 39 and corrispondinlgly located on wich plate. The plate 31 1S. has however no recess in that portion ot its edite., and consequently must he moved baeltwardly to enable the striking head to he projected to the bottom of the corresptnd'tntv recesses of all the other platt-=. l): tracing ont the reeesses in the ,-eteral plates relativelv to each other, it will he found that only one nttlliing head can at one tune he projet-ted sutiieientlv far into the rerum-s to ne iu ti; path of the dept-ceduti har l5 and at last ontv and sometimes t\vo.thrce, or four ol the plates must be withdrawn before any strilt'ingr head can be projected. 'l`he stop plates are normally prevented from moving' bark, and. when they are permitted to mow. back are limited in their travel by slide bars which are independently shown in the Figs. Q1 to 2l inclusive. and to a larger scale in Figs. Q5 and 26. There are tour of these slide bars 45. -lt` 1T. and 4S, superposcd (see Fig. 28) and parallel with the stop plates, each bar acting in eoxijunctit'in with and bein@r of a thickness of two of the stop plates.

The slide ha" l5, Fig. Q1, which works in eonneetion with the stop plates B1 and 32, Figs. 13 and 11, nas the projection 49 at one end equal in width to corresponding projections and 5l (see also Figs. .25 and 26) projecting respectively from the stop plates 31 and 32-the projections being relatively located so that, with the parts in normal position. projection 4) hears one half on projection 50 and the other half on projection 5l. (Fig. and movement of the slide bar to the :right or left for a Space equal to halt' the width of the projection leaves the road clear tor one ot' the plates to move haelt'. Fig. "2o. Exactly similar projeetions. arranged in the same way, are upon the opposite ends of the hars and plates, and are indicated by the same numerals. In the same way the slide bar ttt has projections 5i? and 53 which respectively engage projections 54 and of the stop plate 33 and projections 5ft and .37 of the stop plate 34. The slide bar 4T has projections 56a and 57a which engage projections 5S and 59 of the stop plate 35 and projections G0 and G1 of the stop plate 3G and the slide bar 48 has projections 62 and 63 which engage projections 64 and 65 of the stop plate 37 and projections 6G and '67 of the stop plate 3S.

I will now describe how the slide bars are moved laterally to release the stop plates. Referring particularly to Figs. 1, Q and 5-9,

the hand lever A is pivoted at 69 upon an' arm TQ, whieh is secured toa rocking spindle T1, supported m bearings 72,-73 and 74, Fig. 0 The arm 70 remains statlonary when the lever A is moved about the pivot 69, but i moves with said lever when the latter is moved in a 'forward directiomthereby rocking the shaft 71. The lever A has guide arms 75, 7G, Fig. (i, extendingr rearwardlyv therefron'i, one on each "le of a lever 77, pivoted at 78 to asuitablo part of the framework, the lever 77 thus being moved with the lever rA whe. said lover is moved about the pivot 69, but remaining stationary when the lever is moved in a forward direction. A vertical rocking; spindle 79 is carried by the lever 77, being sup orted near its upper end in a lug extending from the lever and resting at its lower end in a recess therein. Slidelblock 117. having rack Loseier teeth 118, is slidal'ily mounted upon the lever 77, and has apertures through Which the spindle 79 the rear portion of the block being of bifurcated or forked formation, and holding between said bifurcated portions a crosshead 80, which is .thereby elidable on the spindle 79, but is caused to rotate or rock therewith by means of a feather 81, sliding' in a key way 82 in the spindle. The slide block and crosshead are normally held in their uppermost position as shown in Fig. 7, by means of a spring l83, surrounding the spindle 7 9.

The crosshead 80 has pivoted thereto at 84, a rocking Iarm 85, at the ends of which arel formed the projections or detents 86 and 87, adapted to engage with lugs projectingr from the slide har.,l Lt5--48- The slide har 45 has the lugs 99 and 100, the har 46 has the lugs 101 and 102, the liar 47 has the lugs 10S and A104, and the liar 48 has the lugs 105 and 106, See Figs. 21-24 ihclusiw. lVhen the bars 413-48 are in their normal position. the -lugsere supported in tivo seriee, as will lie 25 readily seen. The crosshead 80, and thereby the rocking arm 85, is normally retained in such a position that the'detents 8G and 87 are out of ei'igagement with the lugs ol any of the slide hars, but the crosshead is adapted to be rocked in one direction or the other, about the axis of spindle 79, accordingr to the direction ot move-nient of the lever A, so as to throw one or other of the detents into engaging position with oneof the lugs of one of the `'lido liars. This movement of the eros-sliced is ell'ectcd by means of a lever or crank 9G secured to the upper end of the spindle 79, to which the crosshead is secured, said crank having a pin 97 o normally resting in a fork 98, which is sey cured to an arm 107 pivoted at 108 .upon a standard 10.0. The arm 107 is held down hy atcnsionspriug110. Vlt will lie seen that when the lever is moved about pivot (39. the coaction of the l'orlc 98 and the pin 97 causes the spindle 7!) and tl'icreliy the erosshoad 80. to rock,v so that: one of the detents 80 or 87 engagas with one of tlul lugs on one of the glide buse 'l`he erosshead.' and thereby the spindel;v V17, is. returned to, and held in its normal position, liy means of stop arms il() and 0l pivoti-:l upon hracltets 88 and 8) projecting from the .slide lilock 117, said stop arms pressing against the ends ol the Vcrosshead, under the action of springs 02 and 93, und normally holdinf,r the same in the posiA tion shown in Fig. fl. The Stop arms haveA hooked ends .fl-t and 95. reepectively. which limit their inward movement.

The movement of the levers and 'T7 causes the pin .17 to leave the toi-li' 98. and in order to enable the pin to again enter the fork when tlze levers are returned to normal position, the armiOT is adapted to be raised on the return movement, by the engagement of the cam surface 114 on the upper end of the lever 77, with a pawl/H pivoted to the arm at 112. The arm 107 is nominally held down, as shown in Fig. 8, owing to the engagement of the pawl 111 with a notch 11S in the lever, but to allow movement. of the lever, the pawl is rocked on its pivot, by engagement with the rear face of the cam 114, against the action of spring 116 on the tail piece 11.3 of the pawl, and at the end of the movement of the lever, the pawl is moved h v itsI spring into engagement with the upper surface of cam 114, to elect the raising of the arm 107.

The rockingr arm is normally opposite to the upper slide har 45, and this bar is operated lirst according to the first flash received, either dot or dash. If the signaled letter requires it, the bars 4.6, 47 and 48 are then operated in succession, and in order .to move the crosshead along the spindlev 7i), to cause the rocking arm 85 to successively engage the bars, the pawl 119, 4slidalily mounted on the lever A, is adapted to engage the rack teeth 118 ot' the slide. block 11T. The pawl. 119 is pivotally. mounted in a block 121 which Works in a slot 121h in the lcv-er A, the block 121 having a pin or ]u'ojeetion 121" which projects into a Slot 122 in an arm 123 which is pivoted at its upper end 1211 to the arm 70. A spring 120 tends to move thel block 12.1 to the upper end of the slot 121". lt will be seen from Fig. 7 and trom the dotted lines in Fig. 5 that when tinI lever A is in its normal or` central position, the block 121 and the pawl 11.0 vare held in their lowermost positions, due to the engagement of the pin 121 with the upper end of the slot 122 in the arm 128, the arm being in a vertical position as shown in Fig. 5, and holding the block and pawl down against the action of the spring 12u. `When the lever A. is moved' labout its pivot Y(30, the block 121 and the pin 1212I are moved therewith and consequently, as the arm 123 is pirotally secured to the relatively Stationary arm 70, the pin exerts a cumming' action on the side of the slot 122, with the result that the arm 123 is moved from its vertical position vto an inclined position, as shown in full lines in Fig.

lVhcn the arm 123 is in this inclined position it cannot exert a downward pressure on the bleek 121 and consequently this block vis moved upward in the slot 121 under the action of the spring 120, and the p mvl 119 is ilona-fore moved upwardly a space equal to that of one of the rack teeth 118, the pawl being; pressed into engagement with these tet-th h v means of a suitable spring 119". As 'the lever .X is returned to its normal or central positiin, the pin 121 will exert a anuniug action on the opposite side of the elot 122, which will result in the movement ot the arm 123 to its vertical position, as

shown in dotted lines inl Fig. 5, and as the arni is ,moved to this position, the pin'121e, by contact with thev upper end' of the slot, will be depressed to the position shown in dotted lines in Figo and in .f ull lines in Fig. 7, with the result that the pawl 119 will be moved downwardly and will carry withit the slide block 117 and the parts car ried thereby. 'On tne return of the lever A, to normal position, the paw] is again vinoved downward by the arm 123 to its lower vposition and carries with it, by engagement with teeth 119, the slide block 117 and parts carriedthereby. The pawl 125 acted on by spring 126 holds the block 117 in its various positions. lVhen the lever A is moved forwardly, after the signals for a 'lett-er have been received, the pawls 119 and `125 are disengaged and the slide block andconnected parts are returned to normal position by the spring 83.. YWhen a slide bar has been moved hv one or other of the detente 86 and 87 of the rocking arin S5 to the end of its travel. it is retained by a spring operated bolt which passes into a notch inthe bar. v A

There are tour bolts 127, 12S'. 129, 130 (see Figs. 2i, 10. 11 and 12) slidable in a guide bracket 131 and operated upon respectively by the flat springs 132, 133, 134,9.

` and 135, the bar 445 having the notches 13G and 137, one or other of which receivesthe bolt 127 according to thedirection 1n which the bar is moved.

- 47 has notches 1110 and`141 for the bolt 129,

. /lally connected by a pin 165 vw-itlra rising land the bar 48 has not-ches 142 and 1423101' the bolt 130. The disengagement-of the various bolts 127-130- from the notches of the slide bars, is effected bv the' rocking movement of the spindle 71, diie to thev forward movement .of theleverA and arm 70, the spindle having` fixed thereto an arm 160 seeFigs. 1 and 4,11). whichhas a projection 161, adaptedjnpon theV return4 of the arm to .engage beneath a curved cam 162 projecting from a leve; 163', pivoted at 164 uponthe guidey bracket 131. rllie lever 163 isA pivot.

bar 166 in-engageinent with the ends of tl'i'e bolts, eaehbolt having a' lateral projection 167 (see Fig. 12)' inwhich isa recess 16S for receiving the rising bar 166,' theA recesses each end.

The bar L16 has similar 1 notches 138 and 139 for the bolt 12S, the bar i `163 isin two parts pivotally connected at 170. The slide bars', which are guided in brackets 118 and 149, return to their normal position under the influence of springs at As all the slide bars are siinila'rly furnished at' both ends it will only be necessary to describe 'the arrangement of one end of the uppermost bar. A. projection 150 (see Figs. 25', 26 and 27) from the end of the bar 1.5 engages a crosshead 151 having eyes 152 and and sliding upon thel pins 154 and 155 projecting from the bracket, these pins having upon them spiral compression springs 156 and 157 respec tively. The pressure of the springs on the crosshead is regulated by adjustinginils 158 and 15/9 screwing upon the ends of the pins 154y and 155. The end of all the bars are flush with the sides of tiisguide'brackets'.

` The stop plates from movement Aby .means of rectangular slide blocks .171 and 172 which are located at Ithe ends of the series 'of plat-cs, and are adapted to slide ,in guides 1,73 ati-ight angles to the plates, each bloei; huvingan opening sufficiently large to clear the slide bars. which pass tlirongli them. -Alcver 175 pivoted vat one'enil in the traine ot' the nia-' chine at 176, has an integral stop 177, which bears against the 'end ofthe slide block 171,

are normally prevented and prevents movement thereof, and of the l stop plates, the lever being drawn downwardly by a bridle 17 8 pivoted upon it and connected to the tension spring ,179. Upon the rocking spindle 71 is secured an varin 18() (see Figs. Il, 25 and 27,) which has a recess 181 atits upper end to receive the slide block 171, and in which recess is a friction roller 182 bearing against the end of theV slide' block.

It will be seen that when the handle A is moved forwardly the upper end of the` arin 180 contacts with the leve 175, which is bent downwardly for the purpose, and raises it so that; the stop 177 clears the slide block, which then moves outwardly under the pres sure of the springs operating such ot the stop plates as are. permitted to move rearwardly on account of their respective. slide bars having been operated. Upon the other side off the machine is a precisely similar iarrangement comprising the lever 183 (see Fig. 28) pivoted at 184, having the stop and operated upon by the bridlcf 186v drawn doivn by the tension spring 187. The arm .18S upon the 4rocking spindle 71 has the recess 189 in whichis a friction roller 190 adapted to bear against the end of the slide block 172. The stop plates are returned to lli:

their normal position.. on thereturn inox/rfr nient of the lever A. bv means of the arm`A 1*() and 18S- encafino and movingalie- 'slide blocks 171 andv172.

When the lever Ads returned to its normal position relatively to the' arm 7G, it is retained bya bolt 258 fulcrumed at 259 in the lever A and pivotall connected by unar'ni 2G() to the end of the plunger rod 261, which slides longitudinally through the handle' and has a knob 262 at its upper end adapted to be pressed b v the thumb of the operator when his hand grasps the lever. The bolt 258 slides upon the top of a curved race 263 at the top ot the arm until it coincides with and falls into a recess 264 therein. A compression spring 26.3 is inter osed between the knob and the top of the ever A. The paper ribbon D. upon which the message is to be recorded. is wound upon a spool 191, is carried over a flanged guide slieave 192, and across the top of the machine above an anvil pad 1925 located where the ditierent units of the type will strike when operated. At the opposite end of the machine the paper passes between the flanges of a guide sheave 194` and is pressed upon b v a friction roller 195. which fits between said flanges and is journaled in a loop 15H3 pivoted at one'y end, and, at the other drawn down by a tension spring 197 connected to a bridle 108. The paper then passes between the cutting ofi' Pguillotine, co prising a fixed blade 19t) and a vertically sliding blade 20() operated by a hand lever 201 pivoted at 202, and having a lon-y gitudinal slot 203 which receives a pin 204 projecting from the blade. The blade has slots 205 and 206, which eaehreceive one 0f the tension screws 20T and 208 respectively, rciled springs 209 and 210 upon the respec tive pins pres-ing against a plate 211, which bears against the face of the blade.

The guide shea ve 194 is intermittently rotated by a ratchet wheel 21? which is fixed upon it` and the teeth of which are engaged by a pawl 214 pivoted upon a lever 215 pivoted at one end upon the axle 216 of the guide shea ve. The opposite end of the lever is connected h v a rod 21T with a bell crank lever 218 fulcrumed at 21S). and pivotall \7 connected at its other end 22() to a horizpntal level' 221. the opposite end of which is pivoted at 22:2 upon the end of a projection 223, extending laterally from the side of the lever 180. To prevent over-running ot the paper ribbon spool 191.y a, spring 266 adju-ted by a thumb screw 26T has a brake .shoe 2GB which presses against a boss 269 projecting from the spool.

The carbon ribbon C wound upon a spool 224. extends across the machine in a line with the paper ribbon and beneath the friction guide rollers and 226. and is wound upon the spool 22T. The carbon ribbcn is intermittentlv wound from the spool to spool 227 bv a ratchet wheel 234 (Figs. 1 and 4) fixed upon the spindle 235 of the spool 227 and engaged by a pawl 230 pivoted to an arm 231 journaled at one end upon the spindle 235 and intermittently vibrated from the lever 215 to which it is oonnected by a rod 232 to an arm 233 projecting from the lever In order to provide for the carbon ribbon being rewound from the spool 227 to the spool 224. a ratchet wheel 228 (Figs. 1 and 3) tixed upon the spindle 229 of the spool 221 is engaged by a pawl 23T pi oted upon an arm 238 journaled at one end upon said spindle 22S). 'lhe end of the arm is connected by a rod 239 with a bell crank lever 240 fulcrumed on the frame of the i achine and connected at its end 241 with a horizontal lever 242 (corresponding to said lever 221) pivotally connected at its end 243 to an extension 244 from the arm 188 upon the rocking shaft T1.

The teeth of the ratchet wheels of the respective spools project in opposite directions and by turning one of the pawls upon its pivot out of engagement with the teeth of its ratchet wheel, the spool on that side is free to rotate while the winding is effected b v the pawl in engagement with the teeth of the ratchet wheel ot the other spool. To enable the characters typed on the paper ribbon Vto be seen while the'writing proceeds, the carbonribbon is located alongside the paper ribbon but is not superposed until the moment before al letter is struck.

The movement of the carbon ribbon and its spools is etected in the following way: A har 245 extends across the machine and has journaled upon it said friction rollers 225 and 226. The spindles 229 and 235, of the carbon spools, pass through holes in the respective ends of the bar which bears against the ends of the spools, so that when(r said bar is shifted horizontally, the spools are pushed alo-ng their respective spindles.

To cause the spools to rotate with their respective spindles while they are also free to' slide upon them, the following arrangement is employed: Upon the end of the spindle 229 is an arm 246 at the end of which is an eye through which slides a pin 247 project ing from the side of the spool. A similar arrangement is used in connection with the other spool, the spindle 235 having an arm 248 fixed upon it, which arm has an eye receiving the pin 249 projecting from the spool.

The bar sliitted horizontally to superpose the paper ribbon in the following manner: One of its ends passes through a loop 250 at the end of an arm 251 pivotaliy connected to a lever 252 fulcrumed at and pivoted at its lower end to the end of the horizontal lever 221. Similarlyv the opposite end of the bar passes through a loop 5254 at the end of'an arm pivotally connected to a lever 256 fulcrumed at 2.37 and 'so'prising a series ot slide bars adapted to be type levers adjacent said stop plates, springpivoted at its lower end to thel end of the l horizontal lever 242.

What I do claim and desire to secure by Letters Patent is 1.
